Abstract

Apparatus for processing slag, which is quenched in a liquid-containing vessel, has a forwardly and upwardly sloping chute receiving batches of quenched slag through the medium of a first pusher which is reciprocable along the bottom of the vessel whereby the chute accumulates a column of slag which overflows at the discharge end of the chute. The overflowing slag descends onto the upper side of a first forwardly and upwardly inclined bottom wall in front of a second reciprocable pusher which performs a forward stroke when the first pusher performs a return stroke and vice versa. The second pusher spreads and advances the slag toward and beyond the discharge end of the first bottom wall so that the slag descends onto a second bottom wall which is swept by a third reciprocable pusher. Liquid which is entrained by slag leaving the quenching vessel is permitted to flow rearwardly and downwardly along the bottom of the chute as well as along the two bottom walls so that the material which overflows the second bottom wall is practically free of liquid. Smaller particles of slag which remain entrapped in the liquid descend onto the second bottom wall and are swept rearwardly and downwardly by one or more scrapers which are reciprocated by the third pusher and are lifted off the second bottom wall during forward movement of the third pusher.

Description

(54) SLATER

one

The invention relates to slag removal devices and can be used in the power industry as well as for removal from incinerators.

. A slag remover is known, which contains the s mechanism for moving slags to the discharge edge of the discharge chute and the discharge chute 1.

A disadvantage of the known slag remover is the limited length of the discharge chute, which makes it difficult to transport the slag, especially when placing the bunker site at a considerable distance from the slag removal mechanism.

In this connection, it is necessary to install an additional transport device. When placing a bunker sheet at some height, a high degree of dryness of the scrap is required, which the known transport device does not provide.

The purpose of the invention is to increase the degree of separation of the slag Lb water

The goal is achieved in that a slag remover containing a lead chute and a mechanism for moving the slags to the discharge edge of the lead chute is provided with moving chutes arranged in series and arranged obliquely under the lead chute in which vehicles made with reciprocating motion are installed. Each subsequent porschen is adjacent to the previous one and is located under the moving channel of the previous vessel. Each piston is provided with guides mounted on the side walls and the bottom of the corresponding displacement chute. On the bottom of each moving gutter ledges are made. Attached to the last page; at least a single scraper, fitted with a guide mechanism mounted on the bottom of the corresponding displacement chute. The lower moving chute is provided with a catching tray located at its lower end. In the catching tray installed screw conveyor connected to the reservoir.

Such a shlakoudalitel structure provides for the separation of shlak from its rich water, since the water has time to attach to the shlak, thanks to the inclined troughs to drain.

and the piston does not interfere with the runoff of water, since it lies loosely on the gall. In addition, the slag, the movable lead of the piston rod. The high layer is evenly distributed along the chute to the edge of the rim and the slag layer has a height that does not interfere with the flow of water, which increases the load on the transport device.

The use of several pistons makes it possible to lengthen the transport device to the required value according to the working conditions.

The razmeshenka at the lower end of the most recent shuffle; ayushhey gutter trapping his tray prevents contamination of the drain, the place where the transport device is installed.

The scraper placed in the last moving chute allows small particles to settle on the bottom of the chute and prevent small particles of slag from growing on it. Placing the auger conveyor in the collecting chute prevents overflowing of the collecting tray by small particles of slag and feeds them to the Large slag particles, moved pistons mi.

The stroke of each piston is shorter than the chute, which ensures uniform distribution of slag. Execution on the bottoms of the troughs of the ledges inhibits the reverse slippage of the shnak, whereby the shlak is thrown over the edge at once, and delayed in the front part of the chute.

The invention is illustrated in FIG. The slave remover is schematically represented by the torus. .

The slag remover contains a discharge chute 1 with an ejection edge 2, a mechanism for moving 3, and successively located moving chutes 4 and 4 Under the heads of the output and moving chutes there are prismatic guides 5 and 5 of the rear ends of the moving elements 6 and 6J at the front ends of which are wear-resistant slides 7 and 7, with which the pistons are at rest at the bottom of the moving channels. The direction is provided by additional prismatic guides 8 and 8, which are located at the bottom of the grooves, which facilitate the rectilinear movement of the pistons. The rear ends of the pistons are also fixed on both sides by sliders placed in the spline guides of the lateral walls of the moving troughs. On the underside of the bottom of the hatchway and the moving grooves, right under the edge of the discharge, pivotally mounted ejector 9 and 9 are placed. On the bottom of the moving grooves, ledges 10 and 10 are made to prevent the slal from slipping.

Scrapers 11 and 12 are attached to the last piston b, equipped with guide 13 and 14.

The lower moving chute 4 is provided with a catching lidding 15, located at the lower end of the chute. In the catching tray mounted screw conveyor 16.

Slag remover works as follows

in a way.

Slag quenched with water is fed through the discharge chute 1 by the transfer mechanism 3 to the edge of the discharge 2, from where it is dumped onto the bottom of the first moving chute 4. By means of 6, the slag is fed further along the moving chute 4 and by the ejector 9 to the next moving chute 4. Pulp 6 It is fed to the diverter 9. Small particles of slag, carried away by dripping water, are scraped off by scrapers 11 and 12 from the bottom of the last moving gutter and enter the catching tray 15, from where the screw conveyor 16 is fed to large particles of slag.

The use of the invention allows to increase the length of slag transportation, increase the degree of slag separation from water and increase the load of the transporting device. Due to the uniform distribution of the slag layer in the moving chutes and avoiding its contraction due to the steps at the bottom of the moving chutes, as well as eliminate the pollution of the placement site transport device dripping from the slag water.
